Mutual Capacitance

Mutual capacitance is intentional or unintentional capacitance that occurs between two charge-holding objects or conductors, in which the current passing through one passes over into the other. In transmission lines, when conductors are closely spaced together, the air or material separating them acts as a dielectric, and the conductors act as capacitor plates.

All objects in the universe, conducting or non-conducting, that hold charge with respect to another exhibit capacitance. An object's capacitance increases when another object is brought closer to it. The human body is a great charge-holding object (capacitor) (this biological property is called body capacitance), and sensitive capacitive detectors can be made to function as proximity detectors. The capacitive property of the human body is also helpful in making touch switches, such as those used in touch-activated lamps. The lamp constantly charges and discharges its metal exterior, measuring a change in capacitance.

When mutual capacitance occurs adversely (unintentionally) between transmission lines, this is an example of crosstalk.

Famous quotes containing the word mutual:

    If one considers how much reason every person has for anxiety and timid self-concealment, and how three-quarters of his energy and goodwill can be paralyzed and made unfruitful by it, one has to be very grateful to fashion, insofar as it sets that three-quarters free and communicates self-confidence and mutual cheerful agreeableness to those who know they are subject to its law.
    Friedrich Nietzsche (1844–1900)
